The hope is that with this information readily available, consumers can make purchasing decisions that better align with their values, according to cofounder and CEO Iris Kuo.

"People need to be educated on this topic and understand where their money is going," said Kuo, who said the idea came from a 2013 interview with Sallie Krawcheck that she read in the Washington Post. In it, Krawcheck noted that women told her they'd buy differently if they just knew the company's gender makeup.

"We want to provide actionable data for the huge conversation that's happening right now around diversity," added Kuo.

Gender equality was a hot topic at the first-ever United State of Women Summit on Tuesday. To coincide with the event, the Obama administration, companies and foundations pledged $50 million to support women around the world. That includes 28 companies that signed onto the White House's Equal Pay Pledge, like Amazon(AMZN), American Airlines(AAL), L'Oreal, Gap and Staples(SPLS).

"We should shop and frequent those companies that are doing the right thing," said President Barack Obama during a speech at the summit.

Of the 230 parent companies in LedBetter's database, only 6% -- just 14 -- had female CEOs.

Personal care, apparel and retail are the best industries for women on in leadership roles. H&M's board is 58% women and 41% of its top leadership are female; Gap's board is 36% female and its executive team is 57% female.

Energy and transportation, on the other hand, are the worst industries for gender equity by LedBetter's measures.

But gender representation on the board and the executive team don't always go hand-in-hand.

Make-up brand Revlon(REV) has just one woman on its executive team of 14 people but an above average female board: 33%. Mattel, which makes Barbie, similarly has no women on its executive team, but its board is 30% female.

Update: LedBetter has updated its data to reflect that there is one female executive at Revlon. CNNMoney's story has been updated to include that as well.
